If I made a class, say, MyClass, this class has some members, say, var1, var2, var3. I use this class to create two branches: Br1, Br2 by
MyClass * v1 = new MyClass; MyClass * v2 = new MyClass; tree->Branch("Br1", "MyClass", &v1, 32000, 2); tree->Branch("Br2", "MyClass", &v2, 32000, 2); //then fill them in looping events //write to a file
Okay, then I will try to open this root file in root command line and get access to data stored. If I did
, I was returned a pointer, I guess it is a pointer of “Br1.var1” (since I read documentation, it returns the first leaf name of any branch). How to get “Br2.var1”? I understand that if I use TClonesArray to create the branch, then leaf name will be “Br1.var1” or “Br2.var1”, then it is easy to get data by
. Any hints about this? How to set leaf name as the form of “BranchName.MemName” if I created a branch “BranchName” by my class instead of TClonesArray of my class? I guess I missed something about concept of leaf and branch.
